Yes, I said exactly that....
I was siding with you and suggesting an explanation with supporting example
Edit: Oscar, what you are describing is nothing to do with overbooking. There is limited space in the overhead lockers on board, and it takes time to offload the often excess baggage. It was affecting our OTP. So what they do now is ask for people at the gate to offload their bags into the hold before they get on board the aircraft, and in return can get speedy boarding for what its worth.
And yes, people are still queuing for their allocated seats.
